Hww do you do a ebook or audio book?
Step 1: Find a pre-1923 text you like.
Step 2: Download Audacity, its free open source software. http://www.audacityteam.org/
Step 3: Microphone and talking.
Step 4: Export mp3 files and upload.
I record and upload my audiobooks through LibriVox because they already have infrastructure(such as a mobile app) and a large listener base. I don’t see much need to re-invent the wheel.

They have great how-to’s that describe how to use Audacity to improve the quality of your audio recording in just a few clicks.

There are other ways to upload a work, which I would be glad to show how.
